To all whom it may concern:

Be it known that 1,-Gnonen SGHUBERT, a citizenof the UnitedStates, residingcat Fort Worth, in the county of Tar-rant and State of Texas, have invented certain new and useful Improvements in Self-Feeding Hay- Presses, of which the following is a specification.

This invention relates to an improvement in selfieeding hay presses, of the kind in which aman pitches the hay into the hopper, from said hopper the hay is shifted to the compression chamber by mechanical means. And instead of making use of the usual hopper I use two or more plates or wings, pivoted to the press, (four in the present instance,) 1 and mechanism by which said wings are operated at the specified time. And to use one of said wings as a controlling wing, to close the hopper, and shift the material down to the compression chamber. And, an advance arm or tongue, to close down on the hay, to hold said hay on or in the hopper while said hopper is being closed. And, advance levers pivoted to the press and connected to the side wings of the hopper, and operated by crankarms on the shaft of the controlling wing in such a man- .ner to close the hopper during the first portion of her down to a level of the upper edge of the plunger,

and hold same there until partly compressed.

My invention further consists, in the designing and arranging oi suchmechanism to accomplish these operations; as will be described and pointed out in the claims.

Figure 1 is a top plan view of a portion of a hay press, provided with my improvements, showing the hopper or wings opened out, in position to receive the hay. Fig. 2 is a side view of same, of the near side. The advance movement of the tongue and its operating mechanism being shown in dotted lines. Fig. 3 is a plan view of the controlling wing and its mechanism. Fig. 4 is a view similar to Fig. 2, showing the hopper closed, and in dotted lines the partial movement of the cons trolling wing during the closing of the hopper, and closed down and the tongue locked in position, in full lines. Fig. 5 is a longitudinal vertical section on line 1-1, of Fig. l, with the controlling wing and the tongue down, or as seen in Fig. 4. Fig. 6 is a shiftable member to operate the tongue. Fig. 7 is an edge view of same. Fig. 8 is a plan view of the crank-arm, carried by the pivot oi the controlling wing. Fig. 9 is an edge view of same crank arm. Fig. 10 is a plan view of a crank arm carried on the opposite pivot of the controlling wing. And Fig. 11 is a plan view of the tongue carried by the controlling wing.

Referring to Figs. 1 and 2; 1, 1, represents the usual side plates of the press-body retained by the corner bars, 1 and 1 as in general use. The top plate 2, (see Fig. 5,) is discontinued at a certain point, to provide the rear end of the compression chamber 2.

the usual feed opening or compression chamber 2. The bottom plate 2 is extended a short distance beyond In the front and upper corner of the plates 1, 1, (the power end of the press being considered the front end,) is pivoted ashaft or pivot 3, of the controlling wing 4. Said shaft 3 is preferably formed of an angle bar 3 with its ends rounded in to form the pivots 3, and hollow'or a perforation extending longitudinally through said pivots 3. And with the wing 4 secured onone of the legs of said angle bar 3 On the near and projecting end of the pivot 3is secured a crank arm 5, carrying a roller 6 on its upward prong, with said roller 6 projecting outward in position to engage with a lever later on noted; and having its projecting end 7 bifurcated and slotted 7, for the purpose later on noted. 8 is a prong projecting forward from the heel of said crank arm 5. 10 is a crank arm se-' cured on the opposite end of pivot 3, provided with a corresponding roller 6.

11 and 11 represent advance levers, pivoted to the press back of the rollers 6, 6, and with their free ends curved to a radius of the path of the rollers 6, and their rear and projecting ends pivotally connected by links 12, 12, pivoted in brackets 13, 13, rigid on the side wings 14, 14, said side wings 14, 14, are pivoted to the press by common hinges 15, 15.

16, 16, are spurs on the levers 11, 11, located above the rollers 6 6. The rear wing of the hopper is preferably curved to a radius of its distance from the pivot of the controlling wing, and pivoted to the side of the press in any well known manner at the far end of the feed opening. I i

18 is a spring secured with one end to the wing 17 and with its opposite end to the press, in a manner to draw said wing 17 out a desirable distance. Said wing 17 is drawn in by the arms 19, 19, rigid on the side wings 14, 14, which are formed to a proper curve and of ample length to engage. with said end wing 17.

The controlling wing 4 is preferably formed of a plate with the edges turned up to give rigidness, and with its free end bent inward to'partly tuck down the hay between the beats. Said plate is secured with one end on the angle bar 3. i V

20 is a bar secured with one end to near the center of the wing 4 and projecting with its free end forward and outward, towards one side of the press and. beyond the shaft or pivot 3, 3, and braced out from said shaft a short distance by a brace 21 reinforced by a brace 22 extending from the prong Sto said brace 21.

23, 23, are the usual bridle bars secured to the plates 1, 1, and extending forward, and connected by a cross bar 24, above the plunger bar 25, to receive the top red 26.

27 is a shiitable shaft pivoted in the bridle bars 23,

23, a short distance back of the cross bar 24. 28 is a bellcrank lever rigid on said shaft 27, and connected with its prong 28 by a link 29 to the projecting end of the bar 20, and extending with its opposite arm downward and forward, and to be pressed by a spring 31 on the shaft 27, in to engagement with the serrations 32 on the plunger bar 25 located a proper distance from the plunger.

33, 3,3 are stay rods, connecting the cross bar 24 to the corner bars 1 34 represents an advance arm or tongue, pivoted on the controlling wing 4, and projecting with its body through a slot 35 formed in the wing 4, and resting with its body against the inner side of saidwing 4 when locked in place. 36 is a short and inwardly projecting bulge or curve on said tongue a short distance from its heel, for the purpose later on noted. The pivot of said tongue 34 extends through the hollow pivot 3, and having its projecting end bent at right angles, (see Figs. 1, 2, and 11,) to form a crank 37, with its end turned inward, and having pivoted thereon a bar38 of proper length, and with a head 39 on the opposite end of said bar and in position to engage with the bridle or prongs 7, and with the bosses 40, 40, on said head to engage the slots 7. 39 is an oblong perforation, (see Figs. 6 and 7,) extending through said head 39, to support shiftable therein a rod 42. 43 is a helical spring on said rod 42, resting with one end against the head 39 and with its opposite end against a nut on near the end of said rod 42. 44 is a collar adjustable on said 42 on the opposite side of the head 39.

45 represents a dog or lever centrally pivoted on the spur 8, and projecting with one end forward to engage, when in normal position, with the crank 37; and with its opposite end extending downward to be engaged by the collar 44, and shifted back and retained in position by a spring 46 secured on the brace 22 and extending with its free end to engage said dog 45.

47 is a dog,. pivoted on the bar 1, its body projecting upward to be engaged by the head 39, and having its upper end 48 curved rearward; and with said end 48 of ample area to 'not engage the slots 7 of the prongs 7. Said dog 47 is pressed upward by a spring 49 coiled on said dogs pivot and resting with one end against the body of said dog, and with its other end on the edge of the bar 1 The upward movement of said dog 47 is limited by a lug 50.

51, 51, are latches, located near the free end of the wing 4, and projecting with their free ends through the flanges of said wing 4, in position to engage with the perforations 52 formed at a proper height in the plates 1, 1; and with their inner ends pivoted to the ends of a centrally pivoted lever 53. 54 is a centrally pivoted lever, located at the heel on the wing 4, and projecting with its free end through a slot formed in the angle bar or shaft 3, and connected with its opposite end by a rod 55 to an arm 56 formed on the lever 53. Said latches 51, 51, are pressed outward by a spring 57 resting with one end on the boss 58, and with its opposite end on a boss 59, rigid on one end of the lever 53.

60 represents the usual plunger secured to the plunger bar 25 by a bolt 61; 62 is a brace extending from the bolt 61 to the top plate 63 to retain said plate in position. The front end of said plate 63 is pressed upward by a spring 64 resting against said plate and on a stud 65, rigid on a lug on the plunger 60.

66 is a lug rigid on the under side of the plate 63, and having pivoted thereto a dog 67 projecting with its head 67 forward and through a slot formed in the plate 63, and pressed in such position by a spring 69, resting with one end against the plate 63 and with its other end on a heel 7O ofsaid dog 67.

In operating the press: hay or other fibrous material is deposited on the hopper when open, as seen in Figs. 1 and 2. And as the plunger nears the end of its outward movement the rod 42 is drawn forward, (by mechanism on the front or power end of the press, not shown,) and compressing the spring 43, and as said spring 43 is about compressed the collar 44 moves against the heel of the dog 45 and disengaging the opposite end of said dog 45 from the crank 37, and the continuous forward movement of the rod 42 and the compressed spring 43 will cause the bosses 40 40 to shift inward in the slots 7 and shift the tongue 34 and its mechanism to the position as seen in dotted lines in Fig. 2, thus closing the tongue 34 down on the loose hay on the hopper. The dog 47 will move inward until its free end rests against the prongs 7, after the heel of the head 39 will disengage the said dog 47 and allow the crank arms 5 and 10 andtheir mechanismto shift forward, and the rollers 6, 6, being in contact with the advance levers 11 and 11 will shift said levers to the position seen in Fig. 4, thus closing the side wings 14 14 of the hopper: As said side wings are closed the arms 19 19 engage the end wing 17 and draw it in. At the time the hopper is closed the rollers 6, 6 have arrived at the curved por tion of the levers 11 and 11 and play therein and thus retain the hopper in a closed position. The wing 4 will have moved by this time to the position as seen in dotted lines in Fig. 4. And the rollers 6, 6, having no further resistance will allow the spring 43 to expand again, and the continuous forward movement of the rod 42 will now rapidly close said controlling wing 4 down to the level of the upper edge of the plunger, and shift the material in the hopper to the compression chamber, and the latches 51, 51 engaging the perforations 52 will lock said wing 4 and its connecting mechanism in the position as seen in full lines in Fig. 4. But if there is a heavy resistance in the hopper such as an excessive charge of hay in the hopper; the spring 43 is again compressed and thus allow the closing of the wing 4 to discontinue to a certain degree, in which instance the plunger bar 25 will now move inward faster than the movement of the free end of the arm 28, and thus cause the serrations 32 to engage with the free end of said arm 28 and closing said wing 4 down by direct force, or stop the team by reason of stopping the plunger bar 25. By the time the wing 4 is closed down, the power mechanism will release the rod 42. As the plunger 60 now moves inward, the front edge of the top plate 63 engages the curve 36 and raise the tongue 34 against the wing 4; provided said tongue has not already been raised to said position by the partly compressed material, and again allow the dog 45 to engage the crank 37, and lock said tongue 34 in position. The plunger 60 continuing on its inward movement, it will move the dog 67 against the free end of the lever 54 shifting said end in such direction and thus drawing in the latches 51, 51 by the rod 55 and the lever 53. And the free end of the lever 54 having been pressed in or against the angle bar 3 (see Figs. 3 and 5,) and the line of the pivot of the dog 67 and said lever 54 is below the pivot 3, and thus the onward movement of the dog 67 will open out the wing 4; the angle 3 will now engage the projecting nose on said dog 67 and disengage said dog, and allow the plunger to move on. As the crank-arms 5 and 10 swing back, the rollers 6, 6 thereon move against the spurs 16, 16 and open the side Wings 14, 1 1, and the wing 17 being drawn back by the spring 18. As the crank arm 5 with its mechanism is moved back to the position seen in Fig. 2, the heel of the dog 47 will engage the heel of the head 39 and lock said crank arm in position, with the hopper open as seen in Figs. 1 and 2, until again closed as above described.

The front and lower corner of the wings 14, 14 are cut away to clear the movement of the brace 22.

It will be understood that, instead the angle bar shaft 3 material of any other form may be employed: And various other changes can be made without departing irom the spirit of my invention.
